Lightbulbs in X-ray Light

Medical X-ray imaging works when a body part is placed in between an X-ray source on one side and a camera or detector on the other. Since bone is denser than muscle tissue and skin, fewer X-rays pass through it. This creates a shadow image on the camera behind it. In the developed film negative, the shadow image of the bone looks lighter than the rest of the picture. In this piece of art, light bulbs were placed in a medical X-ray machine. The artist then added color to the individual light bulbs to create the desired effect.
